The predate ARSA's. TRSA's existed when there were only TCA's nad the
FAA hadn't invented ARSA's.

They both predate, and are left-over from, the relevant time periods.

TRSA's are NOT controlled airspace in themselves. Just wannabe radar
service zones.

I don't understand your statement. I've never heard of a TRSA existing in
Class G airspace. All of the ones I've seen have been in Class E airspace,
which certainly is controlled airspace.

It's not an inbetween anything.

You are welcome to that opinion. I happen to disagree. It provides a
higher level of service than that offered by most towers in Class D
airspace, and a lower level of service than that offered by radar facilities
in Class C airspace.

To me, that's exactly what "in-between" means

It's not a class of controlled airspace.

It is a region within Class E airspace where a slightly different type of
radar service is offered from that normally found in Class E airspace. I
would be amazed if there was a TRSA outside of controlled airspace.

Just a charted area where you could get radar services
(which isn't limitted to TRSA's by the way, we have some airports
in the area with approach controls in their class D's that bear
at most a telltale R in their sectioanl data bock).

I certainly don't disagree with your last sentence. That doesn't mean a
TRSA isn't in controlled airspace though.
